H bridge
this circuit is use in dynamo...
imagine that the resistor in the middle is your dynamo and look at the direcrion of current.
_________________________
let..
logic source on the left = LL
logic source on the right = LR
dynamo rotation = DR
CC = counter clockwise
CW = clockwise
S = stop
1 = high
0 = low
_______________________
LL = 1
LR = 0
DR = CC
_______________________
LL = 0
LR = 1
DR = CW
_______________________
LL = 1
LR = 1
DR = S
_______________________
LL = 0
LR = 0
DR = S
